A test manager (for trixy integration tests)
|

|

USAGE:
|

./scripts/tests [OPTIONS] COMMAND
|
||||
|
||||
OPTIONS:
|
||||
--help | -h
|
||||
Display this help and exit.
|
||||
|
||||
COMMANDS:
|
||||
update [TESTNAME]
|
||||
Updates the 'expected.md' file of a test with TESTNAME, if
|
||||
TESTNAME is blank, all tests are updated.
|
||||
|
||||
new TESTNAME
|
||||
Generates a new test from the '.template' directory and drops
|
||||
you into an editor for the 'input.tri' file.
|
||||
It will also generate the 'expected.md' file, after you close
|
||||
the editor.
|
||||
|
||||
ARGUMENTS:
|
||||
TESTNAME | *([a-zA-Z0-9]) := [[ false ]]
|
||||
The name of a test.
|
||||
(The notation above is only really useful, when
|
||||
the shell library is employed to generate
|
||||
a completion script.)
